This disclosure relates to headphones, and more particularly to noise attenuating headphones that may be used when laying down on a side.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
There are many types of headphones intended to maximize comfort and even a few intended for use when sleeping. The existing known headphones, however, have some limitations. These known headphones still include some level of discomfort when pressure is applied to the ear, which can be exacerbated when used for extended time periods such as occurs before or during sleep.
Some known over-the-ear headphones do a good job of blocking external noise while delivering high quality, stereo sound into the ears. They can be designed to be comfortable when worn upright. One can even wear them to bed while laying on one's back. However, most people can lay on their back for a limited amount of time. After a while, most people choose to turn on their side and that's when over the ear headphones have to come off. These known headphones are simply painful or highly uncomfortable while laying on your side.
There are also some known pillows with embedded speakers. These pillow speakers are disadvantaged, however, in that they are flat and do not do a good job of blocking environmental noises or delivering high quality stereo sound into the ears, as only one ear can hear sound at a time, while the other ear is exposed to environmental noise. If the person is laying on their back over that kind of pillow, both ears could hear sound but both ears are also exposed to environmental noises.
Hence, a need exists for comfortable, noise attenuating headphones that can deliver high quality stereo sound into each ear while mitigating environmental noise into each ear.
Ambient noise attenuating headphones are disclosed that may be used when a user is laying down on their side. The headphones include an ergonomic support structure, a noise attenuating structure housed within the ergonomic support structure having a circumferential end configured to surround an ear of the user, wherein the noise attenuating structure comprises a first and second elastic portion, and wherein the second elastic portion has the circumferential end having a material density less than the first elastic portion, and a speaker coupled to the noise attenuating structure.
Certain embodiments of the first and second elastic portions are formed of silicone material having different firmness from having been formed of different material densities.
Certain embodiments of the ergonomic support structure are pillow-like.

In various embodiments, the headphones 10 include an exterior cover 12. The cover 12 can be form fitting. The cover 12 can be formed of one or more different materials. For example, the cover 12 can have a first fabric within inner regions intended for contact with a user's head and a second fabric elsewhere. In various embodiments, the cover 12 can have apertures over the speakers 40. In various embodiments, the cover 12 is removeable, e.g., includes a zipper or tuck-in folds for securing. The cover 12 can have varying thickness relative to different regions, e.g., a thinner thickness within inner regions intended for contact with a user's head and a second thickness elsewhere.
The headphones 10 include an ergonomic support structure 14 that acts to comfortably support a user's head and neck, while laying on their side, house and support the speakers 40, and noise attenuating structure 60, and any electrical components, and encompass the user's ears for noise mitigation. The support structure 14 is preferably sized and shaped to include the first and second void regions 50 and 52 to house the speakers 40 and the noise attenuating structure 60. An interior region of the support structure 14 is size and adapted to receive a user's head and therefore may be partially head-shaped. In one embodiment, the interior region of the support structure 14 is partially recessed, i.e., concaved, around the first and second void regions 50 and 52. The ergonomic support structure 14 may be pillow-like in structure and comfort.
The support structure 14 may be formed of one or more material types that are capable of suitably distributing pressure from a user's head and neck, or portion thereof, including, but not limited to, latex, foam, reticulated or non-reticulated visco-elastic foam (sometimes referred to as memory foam or low-resilience foam), reticulated or non-reticulated non-visco-elastic foam, polyurethane high-resilience foam, expanded polymer foams (e.g., expanded ethylene vinyl acetate, polypropylene, polystyrene, or polyethylene), and the like. The material preferably has a sufficient density and hardness for supporting the head and neck of the user, comfortably.
In various embodiments, the support structure 14 may be formed of materials having different densities, such as a first visco-elastic foam having a first density and a second visco-elastic foam having a second density. One skilled in the art will readily recognize that the selection of a visco-elastic foam having a particular density will affect other characteristics of the foam, including its hardness, the manner in which the foam responds to pressure, and the overall feel of the foam, but it is appreciated that a visco-elastic foam having a desired density and hardness can readily be selected for the an exemplary headphones 10 as desired.
The first and second void regions 50 and 52 can be most any size or shape to secure the speakers 40 and noise attenuating structure 60. In one embodiment, the first and second void regions 50 and 52 can be semi-spherical-shaped or partially, semi-spherical-shaped. In one embodiment, the first and second void regions 50 and 52 can be substantially conical-shaped, partially conical-shaped, or substantially frustoconical-shaped.
As
The noise attenuating structure 60 is preferably secured within the first and second void regions 50 and 52. The noise attenuating structure 60 may be secured within the first and second void regions 50 and 52 using an adhesive layer, for example. The speaker 40 can be secured to the noise attenuating structure 60 using adhesive layer. The cover 12 can be secured over the speaker 40 and the noise attenuating structure 60.
The base support component 62 is sized and shaped to receive the head coupling portion 64. In one embodiment, base support component 62 is sized and shaped to have a void space between the base support component 62 and the head coupling portion 64 in order to contain the speakers 40. The exterior portion of the base support component 62 is preferably sized and shaped to couple to interior surfaces of the first and second void regions 50 and 52. The base support component 62 can have a dome or semi-spherical-shaped interior. In one embodiment, the interior is substantially conical-shaped, partially conical-shaped, partially cylindrical-shaped, and/or substantially frustoconical-shaped.
In one embodiment, wires for the speaker 40 can be bored through the support structure 14 and through a bottom surface 61 of the base support component 62. In this way, any firmness attributed to the wires would be disbursed by the base support component 62 and the head coupling portion 64 when a user is laying on their side. In some embodiments, the wires for the speaker 40 can be bored through sides of the base support component 62 or can be inserted between the base support component 62 and the head coupling portion 64, e.g., inserted within a pre-bored inlet formed on a surface of the base support component 62 and/or the head coupling portion 64. In one embodiment, the battery may be positioned within the support structure for wireless charging.
The head coupling portion 64 preferably includes an exterior surface sized and shaped to couple to the interior portion of the base support component 62. The head coupling portion 64 may be coupled to the interior portion of the base support component 62 using a thin, non-contiguous layer of adhesive. The head coupling portion 64 can have a dome, cupped, or semi-spherical-shaped interior. In one embodiment, the interior is substantially conical-shaped, partially conical-shaped, partially cylindrical-shaped, and/or substantially frustoconical-shaped. In one embodiment, the interior of the head coupling portion 64 has a lower portion that is substantially frustoconical-shaped and a top portion that is substantially cylindrical-shaped. In one embodiment, the head coupling portion 64 includes a lower surface 65 that is preferably circular-shaped and includes an aperture from which sound from the speaker 40 may be directed therethrough.
A circumferential end 66 is sized and shaped to fully encompass the ears, i.e., the circumferential end 66 is configured to press against a user's head, surrounding the ears when in use. The circumferential end 66 partially deforms, or collapses, when pressed, as a function of its hollow interior 67 and material type. In this way, the end may better couple to the user's head. The circumferential end 66 and hollow interior 67 returns to its original shape when removed from pressure, e.g., after being removed from a user's head.
The hollow interior 67 is preferably an annular void space just below the circumferential end 66 and defined by an exterior surface 68 and an interior surface 69. The hollow interior 67 may have any number of cross-sectional shapes including circular or non-circular cross-sectional shapes. In one embodiment, the hollow interior 67 has a rectangular cross-sectional shape with a rounded top, such as shown in
The noise attenuating structure 60 may function to: (1) attenuate ambient noise exterior to the headphones 10; (2) keep sound originating from the speaker 40 from propagating exterior to the headphones 10; and (3) mitigate pressure on the ears when a user is laying on their side. By having the noise attenuating structure 60 formed of two primary components materials may be selected for both components that have different properties.
The base support component 62 and/or the head coupling portion 64 of the noise attenuating structure 60 may be formed from an elastomer material, such as silicone or silicone rubber. In various embodiments, the base support component 62 and/or the head coupling portion 64 may be formed from materials including, but not limited to including, polyurethane (PU) foam, PU foam with a silicone skin, silicone gel with a silicone rubber skin, PU foam with a PU skin, silicone foam, or a thermoplastic (TPE) foam. In one embodiment, any relatively slow-rebounding material which may be deformed and then expand to conform to an original geometry may be used to form the head coupling portion 64.
In one embodiment, the noise attenuating structure 60 is formed of a base support component 62 having a firmness that is greater than the head coupling portion 64. The base support component 62 can be formed of a material have an elasticity that is less than a material forming the head coupling portion 64. In one embodiment, the base support component 62 is formed of material having a material density greater than a material forming the head coupling portion 64. In one embodiment, the base support component 62 is formed of a silicone material having a higher density than the silicone material forming the head coupling portion 64.
In this way, the base support component 62 can be rigid enough to hold the speaker 40 and head coupling portion 64 in place, but flexible and pliable enough to permit the head coupling portion 64 to preferentially flex and move when engaged with a user's head.
In one embodiment, the speakers 40 can be positioned exterior to the noise attenuating structure 60, instead of housed within. In this way, sound may be propagated from the speakers 40 through the noise attenuating structure 60 to the user's ears. Alternatively, apertures from the speakers 40 to the user's ear may be formed on the noise attenuating structure 60, e.g., bored through the base support component 62 and/or the head coupling portion 64. The speakers 40 may be adhered to a bottom surface base support component 62 for securing in place.
